Specification of Letters Patent.

Patented July 9, 1912..

Application filed lluly 21, 1911. Serial No. 639,742.

To all lw/iom, t may concern.'

Be it known that I, JOHN E. citizen of the United States, and a resident county of Cook, and State of Illinois, have invented certain new and useful Improvements in Drinking- Fountains, of which the following'is a speci tication.

My invention 'relates to improvements in sanitary drinking fountains or cups and has yfor its object the production of a `device of this character which will be of improved construction and eiicient in operation.

Other objects will appear hereinafter.

With these obj,cts in view my invention consists'in the combinations and arrangements of parts hereinafter described and claimed.

-.The invention will be best understood by reference to the accompanyin drawing forming a part of this specification, and in which,

Figure 1 is a central vert-ical section of a drinking fountain embodying my invention, and Fig. 2 is a transverse section taken on 1. The preferre fo'rm of mycoiistruction as y illustrated in the drawing comprises an inlet ,tion 'of said nozzle.

chamber 1 of comparativel lar e capacity, said chamber being forme by die substantially hemispherical member 2 which bears the inlet openin 3 adapted to be connected yvith any suitab e source of water supply, and the substantiall hemi-spherical member i which is in threadird connection, as shown, with the member 2. Leading from the chamber 1 is the outlet passage 5 which -is formed in the member 4, saidl passage being screw threaded as shown for the reception of the, cup-like member' 6 which is threaded therein, the member 6 bearing a re stricted discharge opening 7 which leads to the valve chamber 8, the surrounding walls of the latter being formed integral with those of the passage 5. Leading from the valve chamber 8 is the discharge passage 9 which extends vertically, terminating in the nozzle, 10 which is threaded to a nipple 10 formedV at the upper end of the passage 9. The upper end of the nozzle 10 is preferably enlargedas shown and is )rovided with a restricted opening 11 which is positioned at. the bottom of the cup'shaped or recessed upper end por- Thc lower end of thtl passage 9.is governed by thc valve 1 2 which is formed preferably of rubber, said valve Jonxsex, a

being mounted on the valve stem 13 which is reciprocally mounted, said valve being ad- `justably secured in position upon said steril head evidently effecting the desired movcment of said valve.

Surrounding the nozzle l0 is a cup 1T which is in threaded connection as shown with the body of the device, said cu being of a form corresponda substantial y with that of the nozzle biit o greater dimensions so that a considerable space will intervene the adjacent surfaces of said nozzle and cup. The lower end of the cup 17 is in open communication with the upper end or mouth 18 of the drain passage 19, said opening and passage being formed in the body of the device as clearly illustrated in the drawing.

The valve chamber 8 and the discharge passage 9 are in constant communication through the medium otI thc restricted passage 20. lVith this provision it will be seen that although the lower end of the passage 9 is closed by the valve l, a restricted flow of water will he permitted through the pas` sage 20 thereby obviating the possibility of the water in the fountain becoming stagnant and unsanitaiy, a constant flow being periiiitted through thisl provision.y

The discharge passage J -and the drain passage 19 communicate with each other through the openingl through which passes the valve-stem 13. The opening 21 however is 'closed by valves 22 and 22,the former bcing held in position by means ot' the uut 23 which is threaded upon the stein 123, and the latter by means ota shoulder which is formed upon said stem. Said valves are so positioned that the opening 21 will be closed thereby with the stem 13 at either of its terminalsof movement, the valve 22 being adapted to close said opening when said stem is in normal position and the valve 22' to close said passage when said stem is in depressed position. lf desired, the valve 22 and accompanying nut lil thereof may be dispensed with. ln this event however the sages; and a valve operative with said l'low of water when the valve stem is in normal position will not extend up through the passage 9 and nozzle 10, but directly through the lower end ot' said passage Si through the opening or passage 2l into the drain passage 19, the flow not being impeded, the course only thereof being changed. Also itI desired the passage 21.) may be dispensed with in addition to the valve l2 and nut 2d. When this is done however, the continuous flow ot water through the t'ountain will be `stopped but stagnant Water will not be, permitted to lodge in the device. since any ater remaining in the passage Hatter using the t'ountain will immediately drain therefrom through the opening 2l.

A' fountain ot' the construction set t'orth,

lis simple and economical hence may be manufactured at a low cost. 'lha/same is durable and because of the simplicity of the construction is not susceptible to readily becoming inoperable. liv removably securing the member t3 in position, .in the event of the passage therethrough not being suited to the pressure oi water which the fountain is used in connection with, said inember G may be removed and another having an openingr ot' proper diameter arranged in its place. Through the provision lof the in? let chamber l of large capacity relative to the discharge opening;l thereot, a constant flow of water aty a. constant pressure trom said chamber upon depression ofthe valve stem is insured.

While l have illustrated and described the preferredl form at4 construction for carrying my invention into etl'ect, this is capable of variation and modification without departing` .from the spirit of the inven tion. IV therefore-do not wish to be limited to the precise details of construction as set forth, but desire to avail myself of such variations and modifie-ations as come within the scope of the appended claims.

Having described my invention what l claim as new and desire to secure by Letters Patent 'isf l. A device of the class described comprising an inlety chamber; a restricted outletfor said chamber; a valve chamber communicating with said outlet; a discharge passage leading from said valve chamber; a nozzle at the outer terminal of said passage; a valve governing said passage; a cupsurrounding .said nozzle; a drain passage leadingl from said eup, there being a passage connecting said discharge and drainpasfirst mentioned valve, for governing said last mentioned passage; said seeond mentioned valve being so positioned tliatf.Wl1en said lixst mentioned valve is in closed position said second mentioned valve .vill be in open position, and vice versa, substantially as (lCSClllJetl.

2. device of the class described eomprising an inlet chamber; a restricted out let for said chamber; a valve chamber communicating with said outlet; a discharge passage leading from said valve chamber; a nozzle at the outer terminal of said passage; an .exteriorly projecting valve stem; a normallyY closed valve on said stem governing said passage; a cup surrounding said nozzle; a drain passage leading from the bottom ot' said cup, there being a passage es ablishing communication between said discharge and drain passages; and a valve carried by said valve stem governing said last named passage, saidlast named valve being arranged to be in open position when lsaid first named valve is in closed position,
